Had replaced the SSDs about a year ago. It came in for not turning on. PPBUS is at 12.6V. AMP Meter 20V and 0.05 Amps. PP2V5_SSD lines having 2.5V and pulsing every 23 seconds.

Replaced its still the same. Other Ports are now 20V and drawing amps but this corresponding port the amp meter will not turn on. CC1 and CC2 for this port is still low. Device will not turn on now.

Non Working Ports (TA) CC1 diode to Ground is 0.064 and CC2 is 0.161. Low compared to CC1/2 of of there port. (TB) BAD CD3215 ?

3 USB Ports show 5V and 0 Amp Draw and 1 Port USB C the amp meter will not turn on. Client used all 4 ports simultaneously for multiple peripherals always. Machine turns on and charges from the other 3 ports.

PLEASE HELP
